The new Ubuntu is out. It's version 6.06 LTS, in which LTS stands for Long Term Support. For desktops, this means that for 3 years, packages wil be kept up-to-date with security patches. For server users this is 5 years.
I run a few Ubuntu machines myself. Some desktops, some servers. My desktop PC at home was the first one. It started with Ubuntu Hoary, now runs Breezy and in a few days or weeks, when I have time, it will be upgraded to Dapper, which is the code name for 6.06.
Ubuntu is easy to use, based upon Debian, which rocks, and alltogether a great platform for any desktop or server. Really. You should try it!
